Friend of Giz and contributing editor Brendan I. Koerner was on the Colbert Report last night to school Stephen on ways to save the environment. Koerner discussed the paper/plastic debate, using air conditioning vs. windows, and whether it's cheaper to buy CFLs or regular bulbs. Colbert let the green-concious Koerner off pretty easy, but he did manage to raise a fascinating point: If CFLs weren't meant to be licked, why do they look so damn delicious?
